Did I just bust "Are You Smarter Than a 5th Grader?"?

The question was “What family of apes does the following picture belong to?”
The picture was of a male Gorilla.
I said, to myself, “Great Ape family.”
The contestant said, “Silverback!”
Jeff Foxworthy said, “Gorilla would have worked but you gave even more detail!” and said he was right.
I thought, “No! Silverback is a mature male of the Gorilla species!!!” And I went a runnin’ for my Google.

This is what I found.

# Family Pongidae (the Great Apes, including gorillas, chimpanzees, bonobos, and orangutans)
# Genus Gorilla (gorillas and orangutans)
# Species gorilla

Did I just bust “5th Grader” or am I missing something?
